Just decided to purchase this bundle & ended up paying $6.00 for the hell of it. Gotta say, this was much easier than GOG. The promotion sent me a hyperlink, I clicked it, & there were all the games. I chose to download the ZIP of Geneforge 1-5 (98.61MB), & within minutes, I was up & running.

There are options to redeem the games for Desura & Steam as well, but I don't know why anyone would want that.
